  Cycloaddition of Zirconacyclopentadiene with 2-Bromoacrylate, 2-Bromoacrylaldehyde, and 3-Bromofuran-2,5-dione in the Presence of CuCl: A New Pathway for the Formation of Benzene Derivatives and Isobenzofuran-1,3-dione

  摘要：

  Reaction of zirconacyclopentadienes with 2-bromoalkenes in the presence of CuCl afforded multisubstituted benzene derivatives. The reactions of 2-bromoacrylate and 2-bromo-3-phenylacrylaldehyde afforded penta- and hexasubstituted benzenes in good yields. The reaction of 3-bromofuran-2,5-dione with zirconacyclopentadienes gave isobenzofuran-1,3-diones in good yields.

  The invention describes a composition for use in disinfecting a surface for personal use, such as a public restroom facility or telephone. The composition and delivery of the composition provides for the placement of a thin layer of disinfectant which includes a acid-base indicator. The acid-base indicator disappears as the thin layer effects the germicidal activity of the disinfectant. The composition is also rapidly drying, so that the acid-base indicator disappears as well as the disinfecting composition leaving the surface dry. The invention also relates to use of the compositions in a lotion, such as a sunscreen. Use of the acid-base indicator provides a method to visualize where the lotion is applied by color, with the color then later dissipating.

  本发明描述了一种用于消毒个人使用表面的组合物，例如公共洗手间或电话。该组合物及其输送方式提供了一层薄薄的消毒剂，其中包括酸碱指示剂。随着薄层发挥消毒剂的杀菌活性，酸碱指示剂消失。该组合物也具有快速干燥的特性，因此酸碱指示剂以及消毒剂在表面干燥后也会消失。本发明还涉及将该组合物用于洗涤剂，例如防晒霜。使用酸碱指示剂提供了一种通过颜色可视化涂抹洗涤剂的方法，颜色随后会消失。
